Climbing miniature rose plant named &#39;WEKwoagorol&#39;

ABSTRACT

A new variety of Climbing Miniature rose suitable for garden decoration, having flowers of orange and yellow bicolor coloration.

CLASSIFICATION

The present invention relates to a new Rosa hybrida plant.

VARIETY DENOMINATION

The new plant has the varietal denomination ‘WEKwoagorol’.

BACKGROUND OF THE INVENTION

This invention relates to a new and distinct variety of ClimbingMiniature Rose. It has a non-disseminated seedling of my creation as itsseed parent with the following genetic origin (Work of Art×Goldmarie)and as its pollen parent the variety known as ‘WEKtorroc’ (notpatented).

SUMMARY OF THE INVENTION

Among the features which distinguish the new variety from otherpresently available and commercial rose cultivars known to the inventorare the following combinations of characteristics: its excellent colorstability throughout the life of the flower, its unusual orange andyellow bicolor flower coloration and its many hairs on the peduncle andflower receptacle. The plant has a spreading climbing growing habit,suitable for outdoor garden decoration.

Asexual reproduction of the new variety by budding as performed in KernCounty and Pomona, Calif., shows that the foregoing and otherdistinguishing characteristics come true to form and are established andtransmitted through succeeding asexual propagations. ‘WEKwoagorol’ maybe asexually propagated by cuttings, budding and grafting. The buddingand grafting successfully occurred on the plant/rootstock Rosa hybridacv. Dr. Huey (not patented).

COMPARISON WITH PARENTS

The new rose may be distinguished from its seed parent, anon-disseminated seedling of my creation by the following combination ofcharacteristics: whereas ‘WEKwoagorol’ bears medium sized flowers (about4.8 to about 7.3 cm. in diameter) of orange and yellow bicolorcoloration, the non-disseminated seedling bears significantly smallerflowers (about 3.6 to about 4.2 cm. in diameter) of yellow with lightpink blush coloration. The new variety bears double flowers (about 20 to30 petals), whereas the seed parent bears double flowers withsignificantly lesser petalage (about 10 to 15 petals).

The new variety may be distinguished from its pollen parent, ‘WEKtorroc’by the following combination of characteristics: whereas ‘WEKwoagorol’bears medium sized flowers (about 4.8 to about 7.3 cm. in diameter) oforange and yellow bicolor coloration, ‘WEKtorroc’ bears significantlylarger flowers (about 8.5 to about 10.2 cm. in diameter) of deep pinkwith white stripes coloration. The new variety is classified as aclimbing miniature rose with a spreading climbing growing habit withcanes about 150 to about 250 cm. in length, whereas the pollen parent isclassified as a climbing rose with a significantly taller and widergrowing habit with canes about 305 to about 365 cm. in length.

COMPARISON WITH THE CLOSEST COMMERCIALLY AVAILABLE CULTIVAR

The new variety may be distinguished from its closest commerciallyavailable cultivar, ‘MORart’ (U.S. Plant Pat. No. 7,617) by thefollowing combination of characteristics: whereas ‘WEKwoagorol’ bearsmedium sized flowers (about 4.8 to about 7.3 cm. in diameter) of orangeand yellow bicolor coloration, ‘MORart’ bears significantly smallerflowers (about 4.0 to about 5.0 cm. in diameter) of blending orange andyellow coloration. The new variety bears double flowers (about 20 to 30petals), whereas the closest commercially available cultivar bearsflowers with heavier petalage (average about 35 petals).

BRIEF DESCRIPTION OF ILLUSTRATION

The accompanying photograph illustrates the new variety and shows theflowering thereof from bud to full bloom depicted in color as nearlycorrect as it is possible to make in a color illustration of thecharacter. The branches used for the photograph came from 3 to 4year-old rose plants of the new variety grown outdoors in Wasco, Calif.in the month of November. Throughout this specification, colorreferences and/or values are based upon the Colour Chart of The RoyalHorticultural Society (1966) except where common terms of colordefinition are employed.

DESCRIPTION OF THE NEW VARIETY

The following description is of 3 to 4 year-old rose plants of the newvariety grown outdoors in Wasco, Calif. in the month of November.Phenotypic expression may vary with environmental, cultural and climaticconditions, as well as differences in conditions of light and soil.

FLOWER

The new variety usually bears its flowers in clusters of three to sevenper stem. Flowers are borne in regular rounded to somewhat pyramidalclusters on strong medium to long stems (about 32 to about 125 cm.).Outdoors, the plant blooms abundantly and nearly continuously during thegrowing season. The flowers have a moderate tea to slightly fruityfragrance.

BUD

The peduncle is about 2.3 to about 3.7 cm. in length, of slender caliper(about 0.2 to about 0.3 cm. in diameter) and usually erect. It ismoderately smooth, with few stipitate glands and many hairs. Pedunclecolor is between 146C and 146A often heavily suffused, especially on theside exposed to the sun, with between 187B and 187A.

Before the calyx breaks, the bud is about 1.0 to about 1.4 cm. indiameter at the widest point, about 1.4 to about 1.7 cm. in length, andpointed to somewhat ovoid in shape. The surface of the bud bears between7 to 9 foliaceous appendages, few stipitate glands and some hairs,usually with slender entire foliaceous parts extending beyond the tip ofthe bud about ½ or more of its length. Bud color is between 137C and137B often heavily suffused, especially on the side exposed to the sun,with between 187B and 187A.

The sepals are about 1.8 to about 2.5 cm. in length and about 0.7 toabout 1.0 cm. in width at the widest point. The outer surface color ofthe sepal is between 137C and 137B often heavily suffused, especially onthe side exposed to the sun, with between 187B and 187A. The outersurface of the sepal is smooth and bears between 0 to 4 foliaceousappendages with few stipitate glands and some hairs. The inner surfacecolor of the sepal is near 146C broadly bordered by near 137A. After thesepals open, the inner surface color is often heavily suffused,especially on the area exposed to the sun, with between 187A and 187B.The inner surface of the sepal is covered with fine wooly tomentum;sepal margins are lined with some stipitate glands and hairs.

The receptacle of the flower is of medium length (about 0.4 to about 0.6cm.) and somewhat thin to average in caliper (about 0.5 to about 0.8 cm.in diameter). The receptacle is urn-shaped in form. Its surface issmooth with many hairs and very few stipitate glands with somewhat thinfleshy walls. The receptacle color is between 144A and 137B oftenheavily suffused, especially on the side exposed to the sun, withbetween 187B and 187A.

As the petals open (after the calyx breaks), the bud is about 1.2 toabout 1.9 cm. in diameter at the widest point, about 1.4 to about 1.9cm. in length, and moderately ovoid to somewhat globular in form. Thecolor of the under surfaces of the newly opened petals is between 45Band 46B often moderately suffused with between 53A and 187B. At thepoint where the petal attaches, there is a large zone of between 2B and1A. The color of the upper surfaces of the newly opened petals isbetween 26C and 23C sometimes moderately suffused with between 187B and53A. At the point where the petal attaches, there is a large zone ofbetween 3C and 4B.

BLOOM

When fully open, the bloom ranges from about 4.8 to about 7.3 cm. indiameter. Petalage is double with about 20 to 30 petals and about 5 to17 petaloids irregularly arranged. When partially open, the bloom formis moderately globular, slightly high centered to cupped and the petalsare moderately tightly spiraled to somewhat cupped with petal edgessomewhat reflexed outward. When fully open, the bloom form is morecupped and the petals are loosely cupped to slightly undulated withpetal edges moderately reflexed outward.

PETALS

The substance of the petals is moderately heavy and of medium thickness,with upper surfaces moderately satiny and under surfaces matte. Thepetals are about 1.5 to about 2.9 cm. in length and about 1.0 to about2.9 cm. in width at the widest point. Petal margins are entire.

The outer petals are moderately obovate to somewhat rounded in shapewith rounded to sometimes mucronate apices.

The inner petals are obovate to somewhat oblanceolate in shape withrounded to sometimes mucronate apices.

Petaloids are about 0.7 to about 2.4 cm. in length and about 0.3 toabout 1.6 cm. in width at the widest point. Petaloids are irregularlyshaped moderately oblanceolate to somewhat subulate with rounded apices.

The under side of the petiole is rough with some stipitateglands and few small prickles. The petiole is about 0.7 to about 1.6 cm.in length and about 0.1 to about 0.15 cm in width at the widest point.The petiole color is near 146D on the under side and near 137B on theupper side, often heavily suffused on the young leaves with between 187Aand 187B.

The plant displays an above average degree of resistance to powderymildew and rust as compared to other commercial varieties grown undercomparable conditions in Wasco, Calif. The plant's winter hardiness anddrought/heat tolerance are yet to be determined.

GROWTH

The plant has a spreading climbing growing habit with canes about 150 toabout 250 cm. in length with full branching. It displays vigorous growthand the canes are of moderately heavy caliper for the class (about 2.4to about 4.0 cm. in diameter at the widest point).

The color of the major stems is between 146B and 146C. They bear somelarge prickles that are about 0.7 to about 0.9 cm. in length. The largeprickles are angled moderately downward with a short somewhat broad ovalbase; prickle color is between 165B and 164A often moderately suffusedwith between 201B and 201C. The major stem bears many small prickles ofsimilar shape and coloration.

The color of the branches is between 146A and 137B. They bear some largeprickles which are of similar size and shape to the large prickles onthe major stems; prickle color is between 160B and 161B sometimeslightly suffused with near 187D. The branches bear some small pricklesof similar shape and coloration.

The color of the new shoots is between 146A and 137B often heavilysuffused with between 187A and 187B. They bear some large prickles whichare of similar size and shape to the large prickles on the major stems;prickle color is between 160A and 152D often heavily suffused withbetween 187A and 187B. The shoots bear some small prickles of similarshape and coloration.
